bolt 7 operated from a safety slide 8.

The action frame is provided with a rounded forward end as shown at 9 andback of this end a short distance is formed with an opening 10 adapted to receivea lug 11 which is rigid withthe barrels 1 and laand' is shaped to be received within Vthe opening. The forward end of this lug is provided with a trans- Vverse semicylindrical recess 12 and this re-` f'cess bears against a` pin 13 which extends transversely through the frame and serves as a bearingV about which the lug rotates :when

the gun is broken or opened.

Mounted Vto vertically.reciprocate within the rslug 11 is a cocking bolt 14 forwardly of which Vis Va helical spring 15 which normally mpels the cooking bolt in a rearward direction,the movement of the bolt in this direcmit the lug to be removedV from the opening tion being limited by a pin 16, which also precludes the rotation of the bolt by virtue of the flat side 17 on the latter. This bolt is furthermore provided with a recess 18 adapted to cooperate with a lip 19 formed inthe opening in which the bolt operates and bythe cooperation of the recess rand lip, the boltis normally locked against longitudinal'movement until, throughslight manipulation'permitted by lost motion ofthe bolt, the'reces'sA 18 may be disengaged from thelip 19ftoper- 10 in the action frame when, it is desired to dismantle theseparts. 1

4The rear end of the cooking bolt is curved as shown at 2O to constitute a camV surface adapted to cooperate with a cooking lever 21 pivoted at 22 and having associated there-'- with a Thai-'23. This T bar extends transversely of the action frameand overlies both hammers 24. The hammers are also pivoted at 22 and each isY provided with a rest 26 at its forward end and at its back side with a notch 27 Y Bearing against the rest 26 of each hammer is a follower 28 against which a main spring 29 bears. These main springs are housed within the action frame and are of helical type and each followerV has a forward extension'30 which passes through theV corresponding main spring and extends the Aentire distance to the forward end of the action frame as shown best in Figures 1 'and 2. l

' Adjacent the forward end'of each extensionis formed a recess'31 and into this recess projects a portion of the cam 32 pivoted at 33. The purpose of this', connection will be hereinafter more fully explained, but it will be noted'thatf when the extension is moved forwardly the cam will be-moved in a counterclockwise direction. to. permit retraction of a stud'34 associa-ted with each cam whereas, when the extension is moved in a rearmally force its associated hammer into en-I gagement with the firing pin 35. When the hammers fare in retracted cocked position, however, they are locked in place by the sears 5, the forward ends of which engage with the notches 27. j Y Y' j 'j l The cooking is effected bythe operation of opening or breaking the gun, since, when the gun is broken, the cocling bolt 14;. will be bodily swung about the axis of the pin 13 and in so doing will engage with the under side of theV cooking lever 21 and rotate the cooking lever in a clockwise direction as viewed in Figure 3. n This will cause the T-bar 23 to be pressed downwardly against both hammers 24 simultaneously and the hammers will be thus'rotatedV in a clockwiseldirection about theirpivots 22 untilthe sears `5 which are spring pressed, engage with the notches 27. The cookingof the hammers, moreover, retracts the followers 28 and places the main springs'under tension, at the same time forcing the follower extensions 30forwardly to permit retraction of thel studs 34C'.

After the gun is thereafter closed and the triggers subsequently pulled, the sears 5 are released and the main springs force the firing pins into engagement with the shells, but as the main springs operate the follower extensions 30 move rearwardly, rotate the cams 32 and drive the studs 34 forwardly. This forward movement of the studs 34. under the impulse of the main springs is utilized inY accordancel with the present invention to effect a partial release of ejector mechanism adapted to completely eject the shells from the'barrels when the gun is next broken.

It will be noted, however, that only fired shells willbeejccted smc'e unless the trigger" Vhas beenV pulled to fire the shell the correpercussion caps of art. I wish to call particular attention, hownot been properly anchoredv heretot'oreto'th'ef Y part 3. By the present construction, I am enabled to anchor the rear end of the wooden part 37 to the'y bridge 3 by a screw 39 which'` renders the construction much mj'ore rugged than heretofore and makesl the wood lessl liable to displacementr if the gun is inadverftently struck against'some inmioi'rableobject.V As stated, the fore-end iron Sfis skeletonized and' within the slteletonizedpart thereofr` is supported the ejector mechanism to which I have referred. This ejector mechanism will now be described in detail.l

Rigidly mountedon the partB arel two barrel rods 40' and IO which .respectively correspond to barrels land la, and associated with each otV these rod'sis mechanism for ejecting the shell from its c orresp'onding'barrel. Inasmuch as these parts are Vduplicated for the two barrels, a description o fonewill sut'- ice tor'both and for a clearer understanding of the parts, attention is particularly directed to Figure'. It will be noted from 'this figure that the rods extend in parallel 'rela-v tion longitudinally ofthegunbelow the bar rels andon each rodrsmounted agslideblock' 4:1. Each slide block/l1 is' provided with a laterally extending lug 4t2 andan upwardly andl rearwardly extending linger The linger 43' is undercut to form a shoulder 44 at its rear end.

A helical spring 4 [5 is coiled about each of the rods 40 and 10a betweenthe rigid portion of the Jfore-end iron 3 and the slide trod, and these springs serve to normally torce` the slide blocks in arearward direction'. 'The tree endsot the upwardly and rearwardly extending fingers 43 are alined with a circu-k lar rod 46 mounted between the gun barrels -lorlongitudinal sliding movement and this rod i6 is longitudinally slit in a vertical plane so thatrone lateral halt' ot the rod will restr against the rear end of cachot the-'lingers 43. The rear ends of these rod sections carry arf"` cuate ejector sections 47, one of which is associated with the Vbreech offeach barrel and is so disposed as to come flush with the end ofv the barrel when the gun is closedj As a re-y sult the rim ot a shellintroduced Vintothe breech will bear tor a portion of its circumference against the ejectorsections 47, so that. it these'sections `are moved rearwardly, the

shells will be withdrawn trom the breech,

and if the-'operationis rapid enough the n10- i Y mentum of the'shell will snap it free troni the 2.

Simultaneous with BO (see Figure 1) move rearwardly and swingV the operation of the hammers, the extensions the cams 32 against the studs 34.; If pressure is applied to the studs, the bell cranks 51 are tr1pped.(see Figure 2) to disengage the lugs 42iof the slide blocks 41V which form part of,V the ejector mechanism. The sides 41immedi`- ately move rearwardly a short distance to y laterally in the usualmanner to unlock the 4 barrels for pivotal'movement withirespect to the actionframe andthey gun is broken.

' AsV the 'barrels pivotally move on the pivot pin 13. the horn 49 (seerFigure 3) engagesV with the shouldersY 48of the ejector rodY sectionsv and these sections are slowly moved rearwardly until the gun is about half way open by which time .the shellsfwill have been extracted a distance sufficiently to permit them to Vbe grasped and withdrawn by the fingers of the hand.A If itis desired to forcibly eject the shells, pivotal movement of the barrels, i. ej., a further opening of the gun,4 will effect this result. In otherwords, con-` tinued pivotal movement of the barrels will cause the pawls 54 to engage with the shoul Y der 55 (see Fig. 4) and the pawls` V*willbe tripped, so as to disengage the'nose of both pawls from the shoulders 44 of thev ejector fingers.

During the foregoing operation of breakthat the cams 82am returned tothe position Y of Figure 1 wherein they are withdrawn sufficiently to permit re-engagement of the bell crank levers 51 with the lugs 42 of the ejector l slide blocks as soon as the blocks are retracted andthe springs40 retensioned.f,.These springs are reltensioned during the closingof the gun,

The gun thus far described may be equipped with any suitable top-lever or top lever barrel serving the usual purpose of lockingthe gun in` closed position. Under prior practice, however,-the assembly of the top lever and its barrel has constituted considerable annoyance because of the skill required in the 4making of the assembly and I have accordingly in` corporated into this gun a highlynovel form of tcp lever barrel construction which overcomes the disadvantages to which Ilia-ve referred. This construction: will now be described in detail K Y The'top llever 56V has a transverse slot 57 in its under side and 'itis secured yto the top lever .barrel 58 by meansfof a screw 59, said barrel having a polygonal projection which extends into the slot 57 so asto` lock the'top lever a'g'ainst'relative rotation to the barrel. The barrelis provided at its bottom witha head 60" having a transverse slot 61. The sides of the barrel are provided `with two shoulders 62 and 63, the former of which cooperates with the push rod 64 which extends rearwardly to control thesafety'rcatch of the With the other Vshoulder' `63 is asso- The action frame is drilled asshownat 67 and the spring follower is introduced Ainto the'passage thus produced in such manner that the spring and follower will act' against the shoulder 63 see Fig. 8) to normally impel the top lever into a position wherein-its forward end` 68 will interlock with a transverse slotin the rear tang ofthe gun barrels.'

VThis arrangement greatlylfacilitates the assembly of the parts. Thespring'66 and follower 65 are iirst vintroduced into' the passage 67 andthereafter the barrelis introduced into its bearing in theV actionframe from the underside thereof.' j A suitable tool, such lor) llO

an angle screw driver, is then engaged with the slot 6l of the barrel and the barrel is-.rotated until it is in the desired position; whereupon the top lever is brought into a position wherein its transverseslot interits with theY barrel and the screw- 59 isthen introduced and tightened to `bind the parts together with the spring 66 under tension and in Va condition tornormally force rthe top lever into locale ing position. v. Y

The head of the top lever bai-relis provided with a cut out 69l with which the top lever latch is adapted to cooperate. This latch is in the form of albolt() having a head 71. The bolt extends upwardly through Vthe action frameand is provided with a'nut 72 operating in a recess 73 and positioned in the recess below the nut is a'spring 74 which normally tends to elevate the bolt intozthe vpath of the rear tang of the barrels.-4 When Y the gun is closed and the topV lever in locking position, the head 60 of the to-plever barrel 58 will o-verlie the head 7l of the latch, but when the top lever is swung to one side to 11nlock the tangof the barrels the cut out 69 (Fig. 9) willregisterwith the head 'Il of the latch,vso` thatwhen the gunis broken thel spring 74 will lift the bolt 70l and .its head 71,

will enter the .cut out 69 and` will serve toy loc-k the top lever inr unlocking .position until the gun is again closed, during which operation the rear tang of the barrels will force the bolt 70 downwardly to release the barrelV and permit the top'v lever to re-l'ock` the` gun. in closed position. This is a very simple and eco# nomical construction, containing no partsk apt to get outvot order and insuring-,complete efficiency at all times. Moreover, the parts may be readily assembled withoutthe exercise of mechanical skill on'the partl of the workmen... Y
